OC usb expension and 2nd 3rd MC inputs late in sioc monitor?

[AndyCYXU]

For people with multi mastercards and USB expansion cards a question.

I have currently 3 master cards hooked to USB expansion cards but when i initially run SIOC Monitor to check switches etc... only the 1st master cards shows inputs currently ON (green) 2nd and 3rd mastercards show initially all inputs OFF (white) i actually have to flip switch that was ON to OFF then back to ON for it to show ON or turn the rotary switch for example.. after that everything works great but the initial start up shows all being off for second and third mastercard...

if for example i connect 3rd mastercard to 1st input on usb expansion card it gets recognized right away position of switches on or off so its not the wiring problem... then again cards connected to 2nd and 3rd show initially OFF...

main problem with it is that SIOC when run after fsx starts will move all switches to OFF on the panel in FSX for the given switch controlled by cards 2 and 3...

not sure what the issue could be any help is appriciated

Thanks
Andy

update..

if i start SIOC then go to SIOC monitor then choose my USB expansion card as explained above all inputs are OFF on mastercard 2 and 3 but i just noticed with sioc monitor running if i unhook and hook back up card 2 and 3 poof all INPUTS are recognized for the state they are in ON or OFF etc....
faster way then flipping each switch back to off and on etc.. still doesn't seem wright..

Hi Andy,

I have 4 Master Cards on one usb expansion card and 2 on another. SIOC Monitor is indicating switch positions at every MC.

However, in my cockpit I have some inputs (just a random few) that at start up (only) do not pass their (closed) value to SIOC. But for me that's not a big problem because my lekseecon program forces all switches in the sim (767) to the positions of the real switches in my cockpit.

I believe what you are describing is a known "issue", though I thought it only applies to a few switches. I recall in the mists of time that if you force a reset of the expansion card (sw1) then sioc will reread correctly all switches etc. If this is correct (I do not guarantee this!!!) then you could wire one of your switches to this jumper and give it a try.

ok so i found the jumper.. but how do i go about doing it.. ?

with card plugged into USB..? unplugged...? the sw1 is a 3 pin so i am not even sure which ones to "short/connect"...

reset microchip that sound scary... i hope i don't have to program them after... thats way beyond my pay-grade !!!

i sent email to OC see what they say also... google found nothing on this

no mention in manual other then • SW1 = Microchip reset (not used habitually). that's it...

EDITED
ok NVM i shorted it just made a DING-DONG of USB disconnect then I removed jumper few seconds later and just went back ding-dong and nothing no change

That is a shame - I suspect that the original post describing this fix may have disappeared when OC changed their forum, will look for you anyway. Does anyone else on this forum know if there is a fix??

The fix is, I believe, to reset the mastercard power supply. Apologies for the incorrect statement about the USBExpansion card - hope all is well

The historic OC forum data is still there. See this link

Hello,

Never tried the mod though this seems to be another solution:

Nice if Manolo Vélez is able to fix either the PIC code or do some smart
"moves" in SIOC.

Many thanks for that link. A good solution

David,

Yes, this should work and maybe even without the resistor.
I can't see an obvious reason for the resistor to GND as the selected
TTL Output is either high or low (No 3-state). I may be wrong though

Just add a wire from the selected Output to pin 1 of U10 after cutting the trace.
Nice if someone could test this modification and report back....
